ABSTRACT:
A selectively removable door assembly is provided for completing an air filter housing having a series of interconnected walls for enclosing an air filter, certain of the walls being formed with retaining pockets. The door assembly comprises a door having a main portion and opposed end portions. Each of the end portions is provided with a ridge engageable with a respective one of the pockets on the walls for retaining the door on the housing. At least one of the ridges is resiliently and slidably mounted on the door in a biased snap-fit in its respective pocket such that pushing against the bias of the resiliently mounted ridge will permit movement of the other ridge out of its respective pocket and allow the removal of the door to access the air filter.
